In this paper, we report a case of missing posterior teeth after mandibular fibular flap grafting and implant restoration by means of a digital restorative process, in the hope that the application of digital technology will help the patient to comfortably establish an adapted occlusal relationship.
A 29-year-old male patient developed a left mandibular ameloblastoma measuring 35 mm × 35 mm × 25 mm, which did not invade the surrounding bone tissue, submandibular gland tissue, or lymph nodes. After resection of an 85 mm mandibular segment, the patient was reconstructed using a gastrocnemius flap transfer. He was then referred to our institution for postoperative dental implant restoration. The restorative process incorporated various digital technologies including a digital facebow, intraoral scanner, extraoral scanner, facial scanner, and CAD/CAM systems. Following 1 year post-implantation, the patient received second-stage implantation alongside autologous dermal allograft (ADM) transplantation; subsequently, a temporary prosthesis was fabricated while employing an electronic articulator to accurately transfer occlusal relationships before finalizing with permanent restorations. The integration of digital technology throughout this restorative process enhanced both precision and comfort.
This case study offers an innovative and efficient clinical approach for addressing dentition defect following mandibular reconstruction via advanced digital methodologies.
本文报告1例下颌骨腓骨瓣移植及种植修复后后牙缺失的病例，采用数字化修复流程，希望数字技术的应用能帮助患者舒适地建立合适的咬合关系。
一名29岁男性患者，患有左侧下颌骨成釉细胞瘤，大小为35 mm×35 mm×25 mm，未侵犯周围骨组织、下颌下腺组织或淋巴结。切除85 mm下颌骨段后，采用腓肠肌瓣转移进行重建。随后，患者被转诊至我院进行术后牙种植修复。修复过程采用了多种数字技术，包括数字面弓、口内扫描仪、口外扫描仪、面部扫描仪和CAD/CAM系统。种植术后1年，患者接受二期种植及自体真皮移植；随后，制作临时修复体，同时使用电子咬合架精确转移咬合关系，最终完成永久修复。在整个修复过程中整合数字技术提高了精度和舒适度。
本病例研究为通过先进数字方法解决下颌骨重建后牙列缺损提供了一种创新且高效的临床方法。
